Networking ABCs

There are 15 entries for the tag Networking ABCs

In yesterday's post, I finished up my Networking ABC's with the final post of Z.  For those of you who can't find my ABCs tag list on my blog, I figured I'd list them all for you in one place.  A is for AuthB is for BINDC is for Cookie PersistenceD is for Dynamic Ratio Load BalancingE is for EncryptionF is for FirewallG is for GatewayH is for HTTPI is for iRuleJ is for JabberK is for Keep-AliveL is for LatencyM is for Man in the Middle N is for Nagle's...

Today's word in the Networking ABC's starts with the letter Z.  This entry will round out the 26 entries in the Networking ABC's series so I wanted to make sure I got a good one for Z.  When one thinks about computer networking, switches and routers come to mind.  But what makes the whole internet thing work resolves around resolving user friendly domain names into network addresses.  Products such as F5's Global Traffic Manager do all the hard work so your users can get to your site regardless of the geographic location.  The information where these domain entries are...

Today's word in the Networking ABC's is the letter Y.  It took me a long time to find the right networking term that starts with the letter "Y".  A few folks mentioned using "Yank" (as in Yank the cord) or "YMMV" (for Your Mileage May Vary) but I wasn't satisfied with those so I waited.  Finally I came across a term that I thought deemed satisfactory for the Networking ABC's.   The work for today is "Yobibyte".  The Yobibyte is the largest unit of measurement for computer data and seeing how we are immersed in data day and...

Today's word in the Networking ABC's is the letter X.  There really aren't that many words that start with X so my choices for today was limited.  But, luckily for you all, there is one word that stands out as a necessity for application servers hosted behind HTTP proxies.  The "X-Forwarded-For" HTTP header is used to allow a proxy server to inject the true originating IP address of a client connection into the HTTP request allowing the application server to know the callers true identity. "X" is for X-Forwarded-For X-Forwarded-For Pronounced: Eks-Fôr'wərd-ed-Fawr The X-Forwarded-For (XFF) HTTP header...

The letter for the day in the Networking ABC's is the letter "W".  WAP, Web, Windows, Wireless, and WMI are common W words but for today's word I chose the one that makes disaster recovery as well as localized service possible: WAN or Wide Area Network. "W" is for WAN WAN Pronounced: Wahn A WAN, or Wide Area Network, is a computer network whose communications links cross metropolitan, regional, or national boundaries.  WANs are used to connect LANs (or Local Area Networks) and other types of networks together, so that users and computers in one location can communicate...

The letter for the day in the Networking ABC's is the letter "V". Vary headers, verification, and VLAN's find a home with the letter V, but I opted for a word that enables scaling of websites by virtualizing the resources.  Todays word is the word "VIP"   "V" is for VIP VIP Pronounced: vip VIP, not be confused with V.I.P. or Very Important Person, stands for Virtual IP.  A Virtual IP is a mechanism to allow for scalaing and maintenance no a physical resource by virtualizing the access to that device.  A server is accessed by it's network address. ...

Today's letter in the networking ABC's is the letter "U".  UDP, UIE, and users are popular words for this letter, but I opted to a word that most folks use every day but don't necessarily know it.  If you open a browser and connect to a website, you are making use of the word URL. "U" is for URL URL Pronounced: yōō'är-ěl' URL, or Uniform Resource Locator (or also known as Universal Resource Locator) is, in popular usage, a synonym for Uniform Resource Identifier (URI).  A URL begins with a scheme name that defines it's namespace, purpose, and...

Today's letter in the Networking ABC's is the letter "T".  Other words beginning with "T" that would have worked today are TACACS, TMM, trunk, TCP, throughput, traffic, and ToS.  But, being a developer at heart, I opted for the word that I use on an almost daily basis.  The word for today is the programming language of iRules: TCL. "T" is for TCL TCL Pronounced: Tik-uhl Tool Command Language (or TCL) is a scripting language created by John Ousterhout who devised the language "out of frustration with programmers devising their own (poor quality) languages intended to be embedded...

Today's letter in the Networking ABC's is the letter "S".  For today's word I skipped SCTP, SNMP, self IPs, security, SIP, SNAT and spanning tree and opted for one that touches everyone who browses on the Internet.  Today's word is SSL for Secure Sockets Layer) and forms the basis for encrypting Internet traffic. "S" is for SSL SSL Pronounced: Es-Es-El SSL (Secure Sockets Layer), and it's successor TLS (Transport Layer Security) are cryptographic protocols that provide secure communications on the Internet for such things as web browsing, email, instant messaging, and other types of data transfers.  Developed by...

Today's letter in the Networking ABC's is the letter "R".  I could have went with redundancy, RADIUS, rate class, router, or round robin, but I opted for a term that has to do with optimizing media transmission across the network and that's really important for us here at DevCentral as we are all about media!  The word for today is RTSP or Real Time Streaming Protocol "R" is for RTSP RTSP Pronounced: Ahr-Tee-Es-Pee RTSP, not to be confused with RSTP or SCTP, stands for Real Time Streaming Protocol.  RTSP, developed by the IETF and defined in RFC...

The letter for today in the Networking ABC's is the letter "Q".  There wasn't a big selection of Q words with regards to the networking world.  I could have went with queue or query, but those didn't have the umph that Quality of Service does.  So, the word for today is the abbreviation for Quality of Service: QoS "Q" is for QoS QoS Pronounced: Kyoo-on-es The Quality of Service (QoS) level is a means by which network equipment can identify and treat traffic differently based on an identifier.  QoS is the ability to provide different priority to different...

The letter for today in the Networking ABC's is the letter "P".  "P" has a lot of words that relate to networking such as Persistence, Pipelining, Ports, Packets, and PAM but I chose the following word because it had the best picture associated with it.  Today's word is "Pool" "P" is for Pool Pool Pronounced: Pool In networking terms, a pool refers to a logical group of pool members.  A load balancing system will balance requests to the pool members within a pool based on the load balancing method and persistence method that is chosen as part of...

The letter of the day in the Networking ABC's is the letter "O".  While OSCP, Optimization, and OpenSSL were good choices, I opted for a word that refers to minimizing the network overhead for backend servers. "O" is for OneConnect OneConnect Pronounced: Wuhn-Kuh-nekt The OneConnect feature optimizes the use of network connections by keeping server-side connections open and pooling them for reuse. OneConnect was originally designed to allow sharing of server-side HTTP keep-alive connections which otherwise would sit idle or time out waiting for that single client to make a new HTTP request (connection pooling) and also...

The letter for today in the Networking ABC's is the letter "N".  For "N", there are NATs, netmasks, and NNTP servers, but I opted for a word that's common to those who have dug into the implementations of TCP stacks, but may not be known to the rest of the human race.  This week's word is Nagle's Algorithm.  Without it, the web would be a much slower place. "N" is for Nagle's Algorithm Nagle's Algorithm Pronounced Nay-gullz Al-guh-rith-uh-m Nagle's algorithm, named after John Nagle, is a means of improving the efficiency of TCP/IP networks by reducing the number...

Today's letter of the day in the Networking ABC's is the letter "M".  Unlike it's siblings MD5, MAC, and Monitor, today's word is actually a phrase that is important when privacy is concerned.  Today's word(s) is(are) "Man in the Middle". "M" is for Man in the Middle Man in the Middle Pronounced: Man-in-th-uh-mid-l The man-in-the-middle attack (also known as a bucket-brigade attack and abbreviated MITM) is a form of active eavesdropping in which the attacker makes independent connections with the victims and relays messages between them, making them believe that they are talking directly to each other over...
